Can we get a wind-check on that launch? Engineers recently completed testing for the Space Launch System (SLS) rocket in a low-speed wind tunnel at NASA Langley Research Center in Hampton, Virginia for lift-off conditions.

In the 14- by 22- Foot Subsonic Tunnel, researchers were able to measure the influence of ground winds on structures at the launch pad that might impact the SLS rocket.

Prior wind tunnel tests were simplified, but this new testing campaign featured 1.75% scale models of two SLS configurations, Block 1 Cargo and Block 1 Crew, along with the fully 3D-printed 1.75% scale launch tower model.

This data is needed to refine the rocket's guidance and control systems. Engineers are measuring the forces and loads that air induces on the launch vehicle during every phase of its mission.

SLS will be the most powerful rocket NASA has ever built, enabling astronauts to return to the lunar surface with the Artemis program.

SLS is the rocket that will send astronauts to the Moon, Mars, and beyond as NASA continues exploring our universe.

Green Run test will pave the way for NASA lunar missions
Huntsville AL (SPX) Jul 26, 2019
NASA Administrator Jim Bridenstine announced July 25 the agency will conduct a "Green Run" core stage test for the Space Launch System rocket ahead of the upcoming Artemis 1 lunar mission. This is how the Green Run will work: The first eight minutes of every Artemis mission with NASA's Space Launch System (SLS) rocket will begin with core stage and solid rocket boosters producing 8.8 million pounds of thrust to launch the agency's Orion spacecraft to the Moon. NASA will test the rocket's 212 ... read more
